I realize I could have just replied: Yes I have an MOC of MOCs.
I’ll usually rely on direct links or the Index / Launchpad 
note. But I do not underestimate the value of putting together a new dedicated list. It can be soothing; it can lower anxiety. It can reinforce progress. Or it can just be a form of spaced repetition.
My MOC of MOCs has headers like this:
- Top of Mind MOCs
- Recent MOCs
- Ideas MOCs
- Projects MOCs
- Favorite Things MOCs
- Figuring out Life MOCs
- Mind or Body MOCs
- Creation and Storytelling MOCs
- Memory-related MOCs
- Training MOCs
- Books MOCs
- White Dwarf MOCs
One MOC can be under more than one heading of course.
Alternatively, you could make an alphabetical index of MOCs in a separate note. I would manually add the links instead of using backlinks, but that’s just because there’s more control in that.
See what works for you. Please let us know.
